"The national university (UNAM) is located on a sprawling campus in the south of the city, and worth a full day's trip down to explore the area. The campus is also known as Ciudad Universitaria, and it is indeed so big that it is like its own city. Hit a Pumas soccer game in the Olympic stadium, check out the monumental murals by Juan O'Gorman and David Siqueiros, enjoy Modernist Mexican architecture in its full splendor, discover the hidden Sebastián, Manuel Felguérez, and Mathias Goeritz sculptures in the overgrown sculpture garden, and then catch the latest exhibition at the awesome Museum of Contemporary Art (MUAC). In short, there's a lot to do."
